It is expected that the US will push forward with additional sanctions against Iran as its first reaction. The ability to do so has been very much in doubt as China and Russia have expressed reservations about adding to what has been an ever growing litany of sanctions applied over the past decade, but Russia has indicated recently that their opinion may be changing.

IT'S THE AMERICAN WAY!!! I'm a disabled Vietnam Navy Vet and it's been our way since LBJ recalled Navy Fighter Jets from rescuing the survivors of the USS LIBERTY after ISRAEL knowingly ATTACKED the U.S. Navy Ship killing 34 and wounding 174. Our government then covered up the attack and EVERY President since has FAILED to bring JUSTICE to AMERICA for the ISRAELI ATTACK. Israel is NOT our friend. REMEMBER the LIBERTY!!!

Reason Russia has 2nd thoughts—most of the Israelies are Russians.
Russia knows what's in store— Real terrorist Bombings back at their homeland. Just as was done in NaziGermany by PissedoffGerman Jews.
The Russians are no friends of the Iranians :^/
